Abstract

Abstract:

The control signal of fast control power supply (FCPS) in EAST tokamak is decomposed using wavelet multi-resolution. The control signal of FCPS satisfied the demand is obtained, and verified by the simulation and test. Results show that the effect using wavelet is better than other methods.

Key words: Wavelet transform, EAST tokamak, Control signal of PCPS, Filtering

摘要：

用小波多分辨分析方法对EAST快控电源控制信号进行分解，分层设定阈值滤除不符合要求的频率成分再进行信号重构，得到了满足要求的EAST快控电源控制信号，并经过了仿真和实验的验证。结果表明，使用小波变换比使用其他方法更为理想。
